I keep trying to use the int_search function in MiniZinc and it keeps throwing this error

: type error: objective has invalid type, expected int or float, actual `array[int] of var int'

and I don't know how to fix it, the type is an actually array of var int, so it should be fine technically. 

Omg, thank you for responding! I actually figured out my problem haha. I was doing the wrong kind of search. I had put the second search, and what I needed was the first one. 

solve :: int_search(x, input_order, indomain_min, complete) maximize product; 

solve :: int_search(x, input_order, indomain_min, complete) maximize x;
